Each display region 181 comprises a container for displaying data. The mobile computer device 12 receives configuration data from the domestic appliance 10. The size and the position of the display regions as well as the data to be displayed in the containers can be adapted based on the configuration data.

The configuration data is determined by the domestic appliance 10 and/or the behaviour of the user of the domestic appliance 10.

According to another embodiment, the application software (“APP”) comprises an “intuitive display function” for indicating the status of the cooking process. For example, in the beginning of the cooking process the background of the display 18 or touch screen 18 or an indicating portion of said display 18 or touch screen 18 is dark. Then a relative small bright area on the display 18 or touch screen 18 or the indicating portion of said display 18 or touch screen 18, respectively, is activated. During the advancing cooking process the bright area becomes bigger. In the end of the cooking process the whole area of the display 18 or touch screen 18 or of the indicating portion of said display 18 or touch screen 18, respectively, becomes bright. Preferably, the bright area is enhanced from left to right. In particular, a characteristic colour for the area becoming brighter is used. The “intuitive display function” allows that the status of the cooking process may be recognized clearly and from a relative big distance.

According to a further embodiment, the application software (“APP”) comprises a cooking time reduction function and/or a temperature reduction function. In this case, said cooking time reduction function and temperature reduction function require the bidirectional wireless connection 22 between the cooking appliance 10 and the mobile computer device 12, so that the cooking appliance 10 is controllable by the mobile computer device 12. The user may reduce the cooking time and/or the temperature wirelessly via the mobile computer device 12. There is no doubt about the safety, since the energy supply is reduced. In contrast, there is doubt about the safety, if the cooking time and/or the temperature increase, since very high electric power is operated by remote control.

According to another embodiment, the application software (“APP”) comprises a cooking time adjusting function and/or a temperature adjusting function, wherein an increasing of the cooking time and/or the temperature is allowed. For safety reasons the cooking time and/or the temperature may be increased by a slider, which can be activated only by two fingers at the same time. This reduces the danger of an inadvertent activation of said slider.

According to a further embodiment, the application software (“APP”) comprises a display function of statistic parameters. For example, the energy consumption of the cooking appliance may be indicated in relation to other parameters. The energy consumption for predetermined time periods may be indicated graphically or by a table. The energy consumption may be indicated in dependence of the types of food stuff 11 of recipes.

According to another embodiment, the application software (“APP”) comprises an edit function. The user may input and store an own cooking recipe for his own purposes. Further, the user may present own cooking recipes in a social network, wherein photographs of the user and/or food stuff 11 may be inserted.
